The Janissary Tree

During the decline of the Ottoman Empire, eunuch Yashim Togalu uses his palace connections to try and solve a series of thefts and murders.

Long Synopsis:

Istanbul, the year is 1836. Europe is modernizing, and the sultan of the Ottoman Empire feels he has no choice but to follow suit. But just as he's poised to announce sweeping political change, a wave of murders threatens the fragile balance of power in his court. Who is behind the killings? Deep in the Abode of Felicity, the most forbidden district of Topkapi Palace, the sultan--ruler of the Black Sea and the White, ruler of Rumelia and Mingrelia, lord of Anatolia and Iona, Romania and Macedonia, Protector of the Holy Cities, steely rider through the realms of bliss--announces, "Send for Yashim."
Leading us through the palace's luxurious seraglios and Istanbul's teeming streets, Yashim pieces together the clues. He is not alone. He depends on the wisdom of a dyspeptic Polish ambassador, a transsexual dancer, and the Creole-born queen mother. He manages to find sweet salvation in the arms of another man's wife (this is not your everyday eunuch!). And he introduces us to the Janissaries. For four hundred years, they were the empire's elite soldiers. But they grew too powerful, and ten years earlier the sultan had them crushed. Are the Janissaries staging a brutal comeback? And if they are, how can they be stopped without throwing Istanbal into political chaos?
